Climbing perch, Artificial diets, Growth Performances and Feed utilization.
An experiment was conducted to find the appropriate feeding diets and their effects on the growth, survival rate and feed efficiency on climbing perch (Anabas testudineus). The experiment was carried out for duration of 50 days with 3 treatments in 6 still tanks each of size 150×40×40 centimeter using three types of feed (Feed A, Feed B, and Feed C) for 6 replica (TA1, TA2, TB1, Tb2,TC1, and TC2). The initial length and weight were 14.5 ± 0.4 mm and 0.95 ± 0.05 g respectively. The feeds were applied twice a day at the rate of 10 % (initially) to 5% (later on) of the body weight of the fry/day. The results showed that the growth of fry varied significantly (P<0.05) with different diets. Survival rate, SGR, FCR, PER, ADG, Condition factor and Feed efficiency and proximate composition of fish were determined at initial stage, 15, 30, and 50 days of the experiment. Besides several water quality parameter were determined which were found suitable for the experiment as well as for the fishes. From the overall situation, 37% protein containing feed (feed A) was found better for all the estimated parameters.
